CARPET-STRIP ANcHonAGE.

Application led October 30, 1922. Serial No. 597,700.

To all whom t may concer/rt.'

Be it known that I, MAHLoN a citizen of 4the United States, residin atChicago, in the county of Cook and tate of Illlnois, have inventedcertain new and useful Improvements in a Carpet-Strip Anchorage, ofwhich the following is a spec1- fication.

This invention relates to certain improvements in a means for securingto hardened ioors a strip to which the edge of a carpet may be attached.The anchorage of my intake a variety of forms, and be used wit floor,wall, and partition constructions of. various kinds. The severalmodifications shown in the' accompanying O. Kassen,

drawings are suggestive of different conditionswlth which the presentanchorage may It is a primary object of my invention to provide for thepurpose'named an anehorj age which will be secure ,at all times; whichmay be produced and installed at small expense; and which is adaptableas wellto a variety of 'conditions in building construetion. :These andother objects of my invention will appear hereinaftewfrom the speci`fication and claims to follow, taken in connection with the accompan ingdrawings wherein various forms of t e present anchorage are set forth inthemanner following:

Fig. 10 exhibits an'anchorage adapted for use with a slightly modifiedwall or partition construction; and

Fig. 11 represents a still further modification of anchorage adaptedespecially for use adjacent an 'outside wall, of brick or masonriiy. f

he anchorage of this invention is adapted for use with building having aconstruction such, for example, as is shown in Fig. 1,

wherein is shown a concretev floor A from which rises a waill orpartitlon B which ma be formed hollow, or otherwise, in accor ance withusual practice. Near the fioor line grounds C are carried by the wall orpartition as is also 'a plaster coating -D in flush relation therewith.A base board E is also connected with the grounds in the usual manner,and adjacent thereto is a carpet stripF-of approved design having itsrear edge disposed beneath the'base board. A

tongue and groove connection between the base board and carpetlstrip isalso shown in certain figures of the drawings, in accordance with commonpractice, but so far as this' invention is concerned, such a formationmay `be wholly dispensed witlnfsince experience has proven that it maynot be safely relied upon to hold the carpet strip in lace. A

ith a type of building construction such as has been described, theanchorage of my invention may be employed to special advantage. As shownin Fig. 2, it may consist of a plate 10 having ton ues 11 struck up fromits body at points w ich are equidistant from its ends andspaced apartfrom each other about the thickness of thepartition r tile; in addition,each plate end is formed with aplurality of pointed teeth y12 whichupstand for a desired distance. Asshown, these erid wings are three innumber,` and may rise from the Hoor i n the mannershown, or otherwise.By spacingv the two ton ues 11 so as to lie adjacent opposite sides othe tile, the anchorage will be so centered as 1e upon the oor andextend through or below the wall or partition whichv asv 'may beoiset sothat the middle wing is his los

lio

to project its opposite ends for an equal distance on each side of thewall. After erecting the Wall or partition, a carpet strip may beKarranged on each of its opposite sides being driven to position over.the pointed teeth atthe plate end, by which action the teeth becomeembedded in the strip. By offsetting these wings in the manner shown, Ipractically eliminate all possibility of the wood cracking or splittingduring this operation. This strip in these circumstances is heldsecurely in place' upon the floor and may not be pulled away from thepartition even when subjected to the very severe strain imposed by acarpet which is secured thereto in the usual'manner. The addition of thebase board E as is customary, is primarily to present a finishedappearance` but need not in any measure contribute to the presentanchorage except in so far as it may act to prevent its working upwardand thence 'off i of the teeth which grip therewith.

In Fig. 3 I have shown a` slightly modified anchorage construction whichis especially adapted for use adjacent an outside wall B, such, forinstance. as" is formed of. brick. With such a wall 'is associated theusual grounds C, plaster coating D, base board E,

and carpetstrip F, all as previously explained. Ananchorage forthislatter part,

however, may conveniently comprise a plate 15 havinn' upturned teeth 16at one' end thereof, the oppositepla-te end being downwardly turned asat 1t to'provide in effect a flange. In the plate body, it may bepreferred to form one or more holes 18 and likewise otherholes 19 in theflange portion thereof. An anchorage answering to this description isdesigned for installation previous to hardeningr of the floor so thatits flange may be embedded therein in proximity to the wall. In such aconstruction the concrete or mortar isA free to enter the holes-18and19, thus adding to the security of the anchorage. Because each plate islocated close to the wall. it follows that its teeth are lcorrectlypositioned relative to the strip which `is thereafter hammered downthereupon in the manner already' explained. A construction such as this,provides a se.- cure anchorage for the strip such that it will not bedisplaced through pull of the carp\e`t when attached thereto.

T he anchorage forms described up to this point may be modified incertian particulars without sacrifice of the features underlying thisinvention. In Figs..5 to 11. inclusive, are set forth certain formswhich the anchorage may take. these being offered as typical of variouschanges in form, shape, and contour which may advantageously be employedaccording to the conditions created by the building construction withwhich the anchorage must co-operate.

lThe anchorage shown in Fig. 5 is adapted 'A for use with a wallconstruction similar in all .respects to that shown 1n Fig. 1, andaccordingly the parts which are common to .the two figures bear likereference numerals. The anchorage per se consists of a plate 20 adaptedto berested onthe floor with its ends extending laterally to each sideof the wall or--partition- At each plate end is an extension tongue 21which initially protrudes beyond the forward edges of each carpet strip.Upstanding teeth 22 are provided at each end of the plate body inposition to enter the carpet strip when the same is driven downthereupon, as shown in Fig. 5. The platemay-take the form which is shownin Fig. 6 with its tongue 2l extended from a middle position at eachplate end, in which event the teeth lieto either side thereof. lith suchvan anchorage` the extremities 23 of each tongue may be bent upwardlyand around so as to be clinched down upon the carpet strip in the mannershown in Fig. 5. Such a lconstruction serves to reinforce theconnection' between the carpet strip and the anchorage which is providedtherefor.

In Fig. 7 I have shown in plan an anchorage having many characteristicssimilar to that just described in connection with Fig 6. .In thisconstruction use is made of la plate 25 whose extremities 26 are adaptedto extend out beyondv the forward edges of the two carpet strips.Thereafter these extremities are bent up and around so as to beclincheddown upon each strip in the manner described in connection withFig. 5. .Such an anchoragedepends solely upon its clinched connectionwith the two strips to hold-the same in place, inasmuch as I have notprovided any teeth for gripping the strips. It should be borne in mind.however, that the teeth may be added to this construction, in whichevent an. anchorage ,very similar to Fig.l 6 would result. Likewise ifthe tongues of Fig. `6 be omitted, the result will be an anchorage verysimilar to that of Fig. y2. The tongues 11 shown in thislatter-figurewhich serve to center the plate relative to the partition,may or may not be used, according as is desired, the construction ofFifr. 6 suggesting a construc- -tion where suci tongues are whollydispensed with.

Referring now to Fig. 8, the building construction therein showniis inall respects similar to that indicated in Figs. 1 and 5, excepting thatthe wall or partition is indicated as hollow so as to present inner wallsurfaces 27. rIhe anchorage used in such a wall may follow identicallythat which is shown in Fig. 2 with the one exception that the tongues 11are .shown as spaced closer togetherso as to lie adjacent theinnersurfaces of the partition rather than the outer surfaces thereof. Thisdifference, while trifling, is nevertheless suggested at this point, asindicating one further modification which, in some cases, may bepreferred. In this same figure the several teeth 12 are shown as struckup in the same plane, insteadI of being offset. It is not consideredthat this is to be preferred, but is represented as indicative of apossible modification, although very slight, from the exact form shownin Fig. 2.

Fig. 9 sets forth a wall or partition construction in all respectssimilar to that of Fig. 8, it being particularly noted that thepartition used is hollow. The anchorage in this case is intended forholding a carpet strip on only one side of the wall or partition. 'lhisbeing the case the plate 3b therein shown is formed with struck-up teeth31 at one end in position for embedment in the carpet strip, and at itsother end is provided with an up-turned Harige adapted to rest againstone of the inner faces of the wall or partition. In this construction,as elsewhere, the carpet strip backs up to the base board, so that itmay not be further moved toward the wall or partition, while theanchorage which bears against the Aproximate inner face of -thepartition serves to hold the strip against outward movement therefrom.

It may be desired to utilize m invention with wall or partitionconstructlons wherein a combination base board and border is vused. Asan example of this I have .represented in Fig. 10 a wall'or partition Brested upon a floor 36 of concrete, a base board 37 being arranged atthe juncture of the wall or partition with the floor line. This baseboard combines in its construction a border section 38 which is suitablysupported upon a base of mortar or cement. lVith such a con uction it iscommon to mold the floor rwry'th a groove which is thereafter filled byrout or mortar 40, as shown.

A wall and floor construction 'answering to the preceding descriptionimposes special diliculties in the way of an anchorage for a carpetstrip F such as is shown in juxtaposition to the border section 38. Toan- -vchor such a strip in position I employ a plate 41 one portion ofwhich 'is rested on the fioor beneath the border section 38. The end 42of this plate portion is suitably formed for embedment in the mortar, aflange being suggested for this urose. The other end of the plate isprovi ed with a propriate teeth which are adapted to e driven into thecarpet strip when the latter is pounded thereupon. As shown, one ofthese teeth 43 may be elongated to project clear lthrough the carpetstrip, permittin its extremity to be downturned or clinched thereupon.lVith suchl a construction the carpet strip is most securely held inplace. l would have it noted that this provision of an elongated toothwhose extremity projects through the upper side of the strip, therebyadapting it to be clinched thereupon, may be employed with equaladvantage with any of the other constructions herein disclosed.

Another type of building construction where special difficulties areinterposed in the way of an anchorage for the carpet strip is suggestedin Fig. 11. In this case, I have represented a wall or partition'B whichmay be made of brick-or concrete.

The' floor in this construction is shown as monolithic, its ends beingpartly received and supported within the wall, as shown. The carpetstrip in this case is anchored with the aid of a plate 45 havingupturned teeth 46 adapted for embedment therein when the strip is drivendown thereupon.

As shown, the plate is provided with an up- `wardly extending ton ue 47struck from its body, and adapted to ear against the proximate face ofthe wall or partition, thereby centering the anchorage in relation tothe strip which is to be held. This plate which is rested upon the floormay be provided with a crimped or corrugated rear end portion 48, or beotherwise formed in such a manner as to adapt it for reception withinthe mortar space which underlies the first brick that 'is rested uponthe floor. When the mortar is finally placed in this space, the platewill be securely held against displacement so that a firm anchorage forthe strip is provided.

It will be understood that the various formsv of anchorage hereindescribed will each consist of a plurality of plates that are positionedalong the wall or partition at desired intervals so as to effect asecure connection with the strip. Devices of this character may beproduced with the aid of dies at small expense, and possess theadvantage of being readily installed as the buildin operation advances.In accordance wit common practice the base board is adapted to lover-liethe rear edge of the strip, and because of this relationship of theparts the strip cannot work loose from its anchorage unless the baseboard be first removed/ to permit the necessary movements for thispurpose.

I claim:
